[OpenWrt-Devel] [RFC] [PATCH v4] lantiq: IRQ balancing, ethernet driver, wave300

Hello again,

I've managed to enhance few drivers for lantiq platform. They are still
in ugly commented form (ethernet part especially). But I need some hints
before the final version. The patches are based on a kernel 4.14.99.
Copy them into target/linux/lantiq/patches-4.14 (cleaned from any of my
previous patch).

The eth+irq speedup is up to 360/260 Mbps (the vanilla was 170/80 on my
setup). The iperf3 benchmark (2 passes for both vanilla and changed
versions) altogether with script are in the attachment.

1) IRQ with SMP and balancing support:

	0901-add-icu-smp-support.patch
	0902-enable-external-irqs-for-second-vpe.patch
	0903-add-icu1-node-for-smp.patch

As requested I've changed the patch heavily. The original locking from
k3b source code (probably from UGW) didn't work and in heavy load the
system could have froze (smp affinity change during irq handling). This
version has this fixed by using generic raw spinlocks with irq.

The SMP IRQ now works in a way that before every irq_enable (serves as
unmask too) the VPE will be switched. This can be limited by writing
into /proc/irq/X/smp_affinity (it can be possibly balanced from
userspace too).

I've rewritten the device tree reg fields so there are only 2 arrays
now. One per an icu controller. The original one per module was
redundant as the ranges were continuous. The modules of a single ICU are
now explicitly computed in a macro:

	ltq_w32((x), ltq_icu_membase[vpe] + m*0x28 + (y))
	ltq_r32(ltq_icu_membase[vpe] + m*0x28 + (x))

before there was a pointer for every 0x28 block (there shouldn't be
speed downgrade, only a multiplication and an addition for every
register access).

Also I've simplified register names from LTQ_ICU_IM0_ISR to LTQ_ICU_ISR
as "IM0" (module) was confusing (the real module number 0-4 was a part
of the macro).

The code is written in a way it should work fine on a uniprocessor
configuration (as the for_each_present_cpu etc macros will cycle on a
single VPE on uniprocessor). I didn't test the no CONFIG_SMP yet, but I
did check it with "nosmp" kernel parameter. It works.

Anyway please test if you have the board where the second VPE is used
for FXS.

The new device tree structure is now incompatible with an old version of
the driver (and old device tree with the new driver too). It seems icu
driver is used in Danube, AR9, AmazonSE and Falcon chipset too. I don't
know the hardware for these boards so before a final patch I would like
to know if they have a second ICU too (at 0x80300 offset).

More development could be done with locking probably. As only the
accesses in a single module (= 1 set of registers) would cause a race
condition. But as the most contented interrupts are in the same module
there won't be much speed increase IMO. I can add it if requested (just
spinlock array and some lookup code).

2) Reworked lantiq xrx200 ethernet driver:

	0904-backport-vanilla-eth-driver.patch
	0905-increase-dma-descriptors.patch
	0906-increase-dma-burst-size.patch

The code is still ugly, but stable now. There is a fragmented skb
support and napi polling. DMA ring buffer was increased so it handle
faster speeds and I've fixed some code weirdness. A can split the
changes in the future into separate patches.

I didn't test the ICU and eth patches separate, but I've tested the
ethernet driver on a single VPE only (by setting smp affinity and
nosmp). This version of the ethernet driver was used for root over NFS
on the debug setup for like two weeks (without problems).

Tell me if we should pursue the way for the second DMA channel to PPE so
both VPEs can send frames at the same time.

3) WAVE300

In the two past weeks I've tried to fix a mash together various versions
of wave300 wifi driver (there are partial version in GPL sources from
router vendors). And I've managed to put the driver into "not
immediately crashing" mode. If you are interested in the development,
there is a thread in openwrt forum. The source repo here:

https://repo.or.cz/wave300.git
https://repo.or.cz/wave300_rflib.git

(the second one must be copied into the first one)

The driver will often crash when meeting an unknown packet, request for
encryption (no encryption support), unusual combination of configuration
or just by module unloading. The code is _really_ ugly and it will
server only as hardware specification for better GPL driver development.
If you want to help or you have some tips you can join the forum (there
are links for firmwares and intensive research of available source codes
from vendors).
